1952
With the name McCoy, inevitably someone refers to the old adage “the real McCoy.” When
Luther McCoy established McCoy Electronics in 1952, quality and workmanship were of
first importance, to assure that the name “McCoy” would indeed indicate “Real” quality.

McCoy Electronics Company manufactured quartz crystal units, the basic component of
which is quartz, fabricated to certain dimensions and characteristics to control frequency.
These units are used in radio communications and other electronic devices requiring
controlled guidance of the transmitting of data, as in guided missiles and satellites.

The McCoy product line consisted of quartz crystals, quartz crystal filters, switching
assemblies, crystal ovens, glass components for glass enclosed crystal units, and other
frequency controlling devices.

By 1959, two expansions were completed on the original 5,600 square foot plant in Mount
Holly Springs, PA, bringing the total to 23,000 square feet. McCoy employed
approximately 225 people by the end of their first eight years.

1961
On February 1, 1961, McCoy was acquired by Oak Industries Inc. of Waltham, Mass. For
thirty years, McCoy Electronics was operated as a wholly owned subsidiary incorporated
under the laws of the Commonwealth of Pennsylvania.

An ambitious plant expansion program was launched in the early 1960’s, with a brand-new
56,000 sq. ft. facility completed in 1963.

1974
McCoy Crystal opens a 24,000 sq. ft. crystal manufacturing facility in Mercersburg,
Pennsylvania.

1987
Oak Industries Inc. purchased Ovenaire (Ovenaire-Audio-Carpenter, or OAC) in 1991.
Ovenaire manufactures and markets crystal ovens, ovenized crystal oscillators, and
temperature compensated crystal oscillators sold under the Ovenaire trade name. Ovenaire
was originally located in Charlottesville, Virginia.

Oak Industries Inc. purchased Houston Electronics (H.E.S.). H.E.S. manufactures
hermetically sealed glass to metal holders used by manufacturers of quartz crystals. They
specialize in cold weld, resistance weld, and solder seal configurations. H.E.S. was
originally located in Kane, Pennsylvania, and later relocated to Kansas City, Kansas.

Oak Industries Inc. purchased Croven Crystals in Whitby, ONT, Canada.

1991
Oak Industries Inc. consolidates McCoy Electronics, Ovenaire, and HES into the Oak
Frequency Control Group (OFCG). Ovenaire moved to Mount Holly Springs, PA.

1993
Oak Industries Inc. purchased Spectrum Technology, the Goleta, CA subsidiary of Datum,
Inc., on January 12, 1993. Spectrum manufactures hybrid oscillators and TCXOs. Spectrum
consolidated into OFCG and moved to Mount Holly Springs, PA.

1994
Oak Frequency Control split-off McCoy Crystals as a separate business unit. McCoy
operates in Mercersburg, PA.

1995
Oak Frequency Control divided OFC Networks into the Custom Products Group and the
Standard Products Group

1997
In September 1997, Oak Industries Inc. completed the acquisition of Piezo-Crystal
Company. Piezo was founded in 1936, initially to supply frequency determining quartz
crystals to the US Army. Piezo designs and manufactures quartz crystal resonators used
predominantly as timing references in cellular, PCS and VSAT infrastructure equipment.
The company derives a majority of its revenue from the wireless communications market in
which it is a technological leader in the manufacture of high specification frequency control
products. Precision crystals are designed and manufactured in Corning Frequency Control’s
Carlisle, Pennsylvania facility. The Piezo line of precision oscillators are now designed and
manufactured in Corning Frequency Control’s Mount Holly Springs, PA facility.

1998
In October 1998, Oak Industries Inc. completed the acquisition of Tele Quarz GmbH & Co.
KG, recognized as Europe’s leading supplier of frequency control components.

The Tele Quarz line of precision frequency control products are designed and manufactured
in Neckarbischofsheim, Germany.

The addition of Tele Quarz to the Oak Frequency Control Group strengthened Oak’s
already strong position in numerous markets, including cellular infrastructure,
telecommunications transmission and switching, paging radio subscriber and infrastructure,
DECT, automotive, medical, position location, military and space communication, satellite
communications, avionics, and guidance.

1999
Oak Industries Inc. and Corning Incorporated announced on November 14, 1999 that they
had signed a definitive agreement for the companies to merge in a transaction that would
strengthen Corning’s position as a global leader in optical communications. This merger
was completed on January 28, 2000.

2000
Oak Frequency Control Group officially announces its name change to Corning Frequency
Control.

As Corning Frequency Control commemorates its 48th year, we have begun construction
on a 40,000 square foot expansion of our operations facility in Mount Holly Springs, PA.
The addition will contain a state-of-the-art Engineering and Design Center, and will
provide additional manufacturing and administrative capacity.

Today
Operating as a subsidiary of Corning Incorporated, Corning Frequency Control will continue
to be a world leader in standard and custom quartz crystal frequency control products for a
variety of applications. The combined companies employ over 1,300 people worldwide.

Facilities
Eight Corning Frequency Control facilities manufacture precision frequency control
products in North America, Europe, and Asia:

Mt Holly Springs, PA, is a sales, design, manufacturing, and test center for OCXOs,
VCXOs, TCXOs, clock oscillators, and crystal filters, under the Corning Frequency
Control brand name. The facility is ISO-9001 registered, and has been in continuous
operation since 1952.

Neckarbischofsheim, Germany, is a sales, design, manufacturing, and test center for
OCXOs, VCXOs, TCXOs, clock oscillators, and quartz crystals, under the Corning
Frequency Control Tele Quarz brand name. The facility is ISO-9001 and QS-9000
registered, and has been in continuous operation since 1973. Tele Quarz also uses an
outsourcing facility, located in Piestany, Slovakia, which is focused on the manufacture of
crystals for high volume applications.

Corning Frequency Control has three quartz crystal manufacturing locations in North
America. Our Carlisle, PA, location is a sales, design, manufacturing, and test center for
precision SC-cut crystals. The facility has been in continuous operation since 1936. Our
Whitby, Ontario, facility has been designing and manufacturing precision SC- and AT-
cut resonators for precision control applications since 1954. Our Mercersburg, PA,
location designs and manufactures precision AT- and SC-cut crystals resonators. It has
been in continuous operation since 1974.

Corning Frequency Control has an established wholly owned foreign enterprise (WOFE) in
Shanghai, China, serving the rapidly expanding Chinese market. This facility was opened
in 1997. December 2000 will mark the opening of our second China manufacturing facility,
located in the Pudong free trade zone. Both of our China facilities manufacture surface
mount VCXOs under the Corning Frequency Control brand name.
